We have fielded 1000s of units for many different applications from micromachining to LIDAR and Bathymetry to medical applications such as tattoo removal and ablation-based surgical procedures. Tattoo removal generally works, but some tattoos are much harder to remove than others. You must consider both the time delay (Td) and a time jitter (Tj), which is a statistical variation of the time delay depending mostly on: Because of the jitter phenomena, the actual value of the time delay isstatisticallyaltered. The first all-in-one, single-box, microjoule femtosecond laser on the market. Note that this may not provide an exact translation in all languages, Home During the summer of 2021, scientists installed a fast-pulsing laser, about the size of a car, next to a telecommunications tower on Sntis. Short picosecond pulses are ideal for creating high contrast black marks or barcodes on metals such as stainless steel and aluminum. Picosecond lasers use pulse durations of less than 1 nanosecond, which causes predominantly photoacoustic damage (pulses of light that can be measured by changes in pressure ie, sound waves) rather than photothermal destruction of pigment or ink particles (measured by production of heat).
